Course Description: The student will be able to expand a binomial using the binomial theorem, write any term in an expansion, use Pascal's triangle, and understand factorial notations; solve linear, nonlinear and absolute value inequalities using open , closed, half-open and infinite interval notation; work in the rectangular coordinate system, knowing distance and mid-point formulas, equations of a linear function (point-slope, slope-intercept, and the standard form); graph an equation using symmetry, and domain; explain the meaning of function in terms of domain, range, one- one relation; recognize the identity function , constant function even and odd functions and increasing and decreasing functions; know how to shift a graph horizontally and vertically and to reflect and/or stretch a graph; recognize the equation of a circle, locating coordinates of the center and determining the radius; sketch the graphs of and work with piece-wise functions; execute the arithmetic operations (addition, subtraction, multiplication & division) on two functions; determine the composition of two given functions whether a function is one-to-one , and the inverse of a one-to-one function; graph quadratic functions locating maximums or minimums; sketch rational, exponential and logarithmic functions; and know the major properties of logarithms and exponents. Additional topics will be selected at the instructor's discretion may be presented if time permits.
 


Prerequisite:
MAT 099
 

Text: Precalculus, 5th edition
by Larson & Hostetler
Houghton Mifflin Publishing Company, 2001



Attendance:
Perfect attendance is possibly the simplest and most effective way for a student to maximize his or her academic performance. Attendance will be taken at the start of each class meeting.

Tardiness:
Late attendance is a source of distraction to both the students and the instructor. Out of mutual courtesy and respect, please be in your seat and prepared to work at the start of our class time.

Grading Policy:
During the course of the semester there will be:
                               4 - 5  one hour tests
                               6        ten minute quizzes
                               4        calculator laboratories
                               1        final exam

 

Exams:
Four or five exams will be administered during the semester. Missing one of these tests is a SERIOUS matter. Four or five exams will be administered during the semester. Missing one of these tests is a SERIOUS matter. If a student finds it impossible to take a test due to circumstances beyond their control, they should contact the instructor immediately or at the very least, prior to the next class meeting. After this date, there will be no opportunity to make up an exam except through the presentation of a written doctor's certificate establishing a valid medical excuse.
 

Quizzes: Quizzes will be administered during the first ten minutes of class. If a student is late to class on a quiz day, they will have less than the full time to take the quiz. Quizzes are announced in advance. Quizzes will be administered during the first ten minutes of class. If a student is late to class on a quiz day, they will have less than the full time to take the quiz. Quizzes are announced in advance. THERE WILL BE ABSOLUTELY NO MAKE UP ON QUIZZES FOR ANY REASON. A student will receive a grade of zero on a quiz if they miss the quiz or if they leave class after taking the quiz. The five best quizzes out of the six administered will count for twenty points each and be combined to equal one test grade.

 

Homework: Students should prepare for their tests and quizzes by completing all homework assignments in a timely fashion. Homework should be kept in a separate section of the notebook from class notes. Periodically homework will be collected at random. Students will receive a grade of 0,1, or 2 on each assignment depending upon the completeness of the assignment. All work should be displayed for each example. Students should have their assignment notebooks with them at all class meetings. Homework assignments will count for one quiz grade which will not be dropped.

 

Final Exam: The final exam will be cumulative and count for two test grades in the computation of the final mark for the course.

 

Method of Instruction:  The Instructor will present new material with extensive student interaction and participation. Cooperative learning techniques will be used as frequently as time permits.
 


Help!!!!
  1. Get to know your classmates. Exchange telephone numbers.  Form study groups. This strategy has worked very well for students who make the effort to try it.

  2.     Purchase a copy of the Student's Solution Manual which
          accompanies our textbook. This manual has the worked-out
          solutions to all odd numbered questions in the textbook. The   bookstore should have copies.

    3.   Check the hours and days the Math Lab is open and use
           the free help this facility offers.

    4.    Meet with me for extra help during my office hours.

    5.    Check the Houghton Mifflin web site for interactive features specific to our textbook: www.college.hmco.com
